ABSTRACT

Herein is disclosed a virtual embodiment display system comprising one or more image sensors, configured to receive one or more images of a vehicle occupant; one or more processors, configured to determine a gaze direction of the vehicle occupant from the one or more images; select a display location corresponding to the determined gaze direction; and control an image display device to display a virtual embodiment of an intelligent agent at the display location; the image display device, configured to display the virtual embodiment of the intelligent agent at the selected display location according to the one or more processors.

TECHNICAL FIELD

Various aspects of the disclosure relate generally to the use of anintelligent agent for interaction between artificial intelligence andhumans.

BACKGROUND

As vehicles assume functions that had previously been reserved fordrivers, thereby becoming autonomous or semi-autonomous vehicles,communication between vehicle occupant and vehicle assumes greaterimportance. Existing models for such communication tends to reflect adesire for the vehicle to provide a variety of information to the driveras well as the passengers, such as in the context of one or moredisplays, which may display data related to the vehicle's autonomous orsemi-autonomous actions. Occupants may similarly provide information tothe vehicle through one or more controls (buttons and the like) or byinputting information on a screen. In addition, speech recognitionabilities have permitted at least some level of voice-basedcommunication between humans and machines. Whether screen-based orspeech-based, natural and fluent communication requires a point of focusfor communication between the occupant and the vehicle, and the lack ofa point of focus is detrimental to communication.

SUMMARY

Herein is disclosed a virtual embodiment display system including one ormore image sensors, configured to receive one or more images of avehicle occupant; one or more processors, configured to determine a gazedirection of the vehicle occupant from the one or more images; select adisplay location corresponding to the determined gaze direction; andcontrol an image display device to display a tag at the displaylocation; the image display device, configured to display the tag at theselected display location according to the one or more processors.

It is readilyunderstood that any single memory component may be separated intomultiple collectively equivalent memory components, and vice versa.Furthermore, while memory may be depicted as separate from one or moreother components (such as in the drawings), it is understood that memorymay be integrated within another component, such as on a commonintegrated chip.

The term “tag” as used herein to indicate an identifier of theartificial intelligence. The tag may take any form whatsoever. Accordingto one aspect of the disclosure, the tag may have a human or near-humanform. According to another aspect of the disclosure, the tag may have arepresentative form, such as, but not limited to, a cartoon, a drawing,a comic, an avatar, or other figure. According to another aspect of thedisclosure, the tag may have an abstract form, such as one or moregeometric shapes, a design, a logo, or otherwise. The tag may be avirtual embodiment of the intelligent agent.

Current research efforts and industry trends focus on positioning theautonomous vehicle as a trusted social companion, suggesting an effortto help humans perceive intelligent vehicles as representations of asentient being. This requires establishing a natural means ofcommunication between humans and autonomous vehicle. Without firstestablishing a natural means of communication between humans andautonomous vehicles, the perception of the vehicle as a representationof a being is unlikely to be achieved. One meaningful component of thiscommunication is a dialogue management system within the autonomousvehicle. An additional meaningful component is a representation withinthe autonomous vehicle of the vehicle intelligence, thus providing acentral point of focus for one or more human occupants to communicateand interact with the autonomous vehicle. It may be further necessary tocreate the representation in a configurable way, such that adaptationcan be performed as research develops, and to apply to a variety ofvehicle configurations and autonomous vehicle interior designs.

As autonomous vehicles are developed, it has been known to create apoint of interaction between a vehicle occupant and the autonomousvehicle in the form of a screen, said screen typically providingunidirectional information to the occupant regarding the vehicle'sintentions or actions. Various autonomous vehicle implementations havearranged said information in a single screen, or possibly throughoutmultiple screens within the vehicle. Said screen or screens may provideinformation such as, for example, vehicle speed, vehicle surroundings,and any vehicle maneuvers performed by the autonomous vehicle. Suchscreen interfaces have been used in performance and/or tests of avariety of autonomous vehicle levels, including Level 3, Level 4, andLevel 5 driving. Although providing information in this manner to theoccupant may have some utility, it does not approximate human to humaninteraction. As such, effective communication may require severaladditional translational steps, or information may be lost altogether.

Currently used autonomous vehicles may lack a point of focus within theautonomous vehicle for interaction between one or more occupants and theintelligent agent of the autonomous vehicle. Conventionally usedcommunication interfaces, such as screens delivering data, may not besuitable for an occupant to make natural eye contact while communicatingwith the autonomous vehicle, if they lack an embodiment of theintelligent agent of the autonomous vehicle. Furthermore, unless apassenger believes that the conventionally used communication device hasthe ability to see and understand paralinguistic features of language,the passenger will be less likely to use these features which, if usedby the passenger, could facilitate communication between the passengerand the vehicle intelligence. Aspects of this disclosure include virtualand/or physical embodiments of the intelligent agent that serve as apoint of focus system for occupants within the autonomous vehicle, aswell as system components that are designed to capture and utilizeoccupant movements and/or interactions with these embodiments in variousconfigurations. These may result in a more natural manner of interactingwith the intelligent agent of the autonomous vehicle and renderautonomous vehicle technology closer to becoming a trusted companion forhuman beings.

As autonomous vehicle technology is improved, it is anticipated thatautonomous vehicles will perform with Level 4 and Level 5 capability,for which improved communication between occupant and autonomous vehiclemay be beneficial. In addition, in-cabin experiences for vehicleoccupants may become key differentiators for fleet services that will beoffered by various vehicles. Increased occupant satisfaction, as well asincreased or improved occupant-to-autonomous vehicle communication maybe reached by improving communication interfaces to approximate anatural human-to-human communication. Furthermore, by providingoccupants with a point of focus, the gaze of the occupants may beconstrained in order to improve sensing accuracy of in-cabin humanunderstanding scenarios. Such scenarios may be occasions of humanmovement or human gaze behavior, for which the autonomous vehicle mayperform a behavioral analysis in order to gain an understanding of thehuman occupant's instructions, impressions or desires. Such behavioralanalysis may be more successful where the occupant's gaze is generatedwith a particular perspective in mind, rather than when the occupant'sgaze has no specific point of focus. The principles described herein maypermit a vehicle occupant to achieve a higher level of integration with,and control of, the autonomous vehicle system.

FIG. 1 depicts a known vehicle information system 100, as viewed fromwithin an interior of the vehicle. A vehicle with some level ofautonomous vehicle capability may include a communication interface 102,on which information is provided to a vehicle occupant. Thecommunication interface 102 may be subdivided into a number ofinterfaces with one or more dedicated functions, such as depicted in104, 106, and 108. Under this configuration, and occupant within thevehicle turns to the communication interface 102 to obtain informationabout the vehicle and/or any autonomous vehicle functions orcapabilities. Information provided to the vehicle may be provided viathe communication interface 102.

FIG. 2 depicts a vehicle visual tag system according to a first aspectof the disclosure. The vehicle is equipped with one or more imagesensors 202, which are configured to receive images of a vehicleoccupant. The vehicle may be equipped with one or more processors 203,which are configured to receive image data corresponding to the one ormore images from the image sensor 202, and to determine from the imagedata a gaze direction of a vehicle occupant. As will be described ingreater detail, the gaze direction may be calculated based on at leastone of a calculation of occupant body position, head position, and eyeposition. The one or more processors 203 may be further configured toselect a display location corresponding to the determined gaze directionof the vehicle occupant. The one or more processors 203 may be furtherconfigured to control an image display device to display a visual tag atthe selected display location. The vehicle may further include an imagedisplay device 204, which is configured to display the visual tag at theselected display location according to the one or more processors. Thevisual display device 204 may be any device that is capable ofdisplaying a visual tag. The visual display device 204 may include oneor more projectors to project a visual tag on a surface of or within thevehicle. The visual display device 204 may include one or more screens,configured to display the visual tag at the selected location. In thiscase, the image sensor 202 receives images indicating that theoccupant's gaze is directed to a top left area of the vehicle interior.The one or more processors 203 calculate the gaze based on the imagedata, using at least one of occupant body position, occupant headposition, and occupant eye position. Upon determining a direction ofgaze, the one or more processors map the gaze to an interior point orregion of the vehicle and control the image display device 204 toproject a visual tag 208 at the mapped region. In this case, the visualtag 208 is depicted as a human shape. The visual tag may be of anydesign whatsoever. According to an aspect of the disclosure, the visualtag may be given a human or human-similar shape, which may engenderfeelings of trust or relatability within a human occupant. The visualtag may be given a shape including a face, such as with two eyes and themouth, such that the eyes may be directed to appear to look at one ormore regions of the vehicle, or to make eye contact with the vehicleoccupant.

FIG. 3 depicts a vehicle visual tag system according to a second aspectof the disclosure. As autonomous vehicles develop, and as the need forat least intermittent human control of the vehicle diminishes,autonomous vehicle occupants may conceivably relinquish all traditionaldriving responsibilities, such as acceleration and steering.Accordingly, it is anticipated that some or all occupants may sit in aconfiguration other than the traditional forward-facing vehicleconfiguration. FIG. 3 depicts an alternative seating arrangement,wherein one or more occupants may sit in a round 302. In this case, thenecessity to direct attention in the direction of travel may bediminished, which may permit introduction of one or more occupant focalareas 304 within the vehicle. In this case, focal area 304 may be animage display device, such that the visual tag may be projected from thefocal area 304 to a desired location within the vehicle. The focal area304 may be a physical embodiment of a visual tag, such as an embodiedagent.

FIG. 4 depicts a vehicle visual tag system according to a third aspectof the disclosure. The vehicle may be equipped with one or more imagesensors 401, which are configured to obtain one or more images of a useroccupant. One or more processors 402 within the vehicle may beconfigured to receive the images from the one or more image sensors 401and to determine from the received images an occupant gaze. Based on theoccupant gaze, the one or more processors may select a display locationcorresponding to the determined gaze location of the vehicle occupant.The vehicle may be equipped with a plurality of image display devices,which are configured as one or more screens 403-409. The one or moreprocessors may be configured to select a screen corresponding to thedetermined gaze location, and to control the selected screen to displaythe visual tag. That is, rather than projecting the visual tag on apredetermined location, the one or more processors may select a screenat or within a vicinity of the desired location, and to cause theselected screen to display the visual tag.

FIG. 5 depicts a vehicle visual tag system according to a fourth aspectof the disclosure. In this case, the vehicle is equipped with one ormore image sensors 502, which are configured to obtain images of avehicle occupant. The system further includes one or more processors504, which are configured to determine an occupant gaze from the one ormore images. In this case, rather than projecting or displaying an imageof a visual tag, the vehicle may include a physical embodied agent 506,which may be, for example, a three-dimensional representation of avisual tag. According to one aspect of the disclosure, the physicalembodied agent 506 may resemble a human shape. The physical embodiedagent may include at least one of a head, a torso, upper extremities,lower extremities, or any combination thereof. The physical embodiedagent 506 may be located anywhere within the motor vehicle. The physicalembodied agent 506 may be designed as a focal point for paralinguisticgaze of one or more occupants, such that an occupant's gaze is directedto, or conditioned by, the physical embodied agent 506 duringcommunication.

An occupant may directly gaze in a direction other than the physicalembodied agent 506, such as to an area of the vehicle, or to an areaoutside of the vehicle. Element 508 depicts a gaze of an occupant beingdirected to a region outside of the vehicle. The physical embodied agent506 is within a line of sight 510 of the occupant, or the occupantotherwise expresses a belief that the agent to have access to thedirection of gaze. The physical embodied agent may be configured toreceive images corresponding to a vicinity of the vehicle 512 and tocorrelate the occupant gaze 508 with an object in the vicinity of thevehicle 512. Accordingly, the physical embodied agent 506 may beequipped to recognize an occupant's point of focus outside of thevehicle. The physical embodied agent 506 may be equipped with one ormore image sensors on or within the physical embodied agent, or thephysical embodied agent may receive information or data from one or moreimage sensors external to the physical embodied agent. Similarly, anyprocessing necessary for the physical embodied agent may be performed byone or more processors located within or external to the physicalembodied agent.

FIG. 6 depicts a physical embodied agent's correlation of an occupant'sgaze with an occupant's gesture. In situations where the physicalembodied agent may recognize a gaze of a vehicle occupant, thedetermined gaze may be associated with a direction or a vector, whichmay be extended from the occupant in a specified direction, to provideinformation about an object or point of focus of the occupant. Withoutfurther information, however, it may be difficult or impossible todiscern the specific object of focus of the occupant, as the object maytheoretically be any object along a vector or line extending outwardfrom the occupant. Additional information about an occupant's attentionor visual focus may be derived from an occupant's gesture.Disambiguation may be multimodal; for example, language, gesture,posture, and/or gaze may all work together to help a machineintelligence to understand how to ground a passenger's reference. InFIG. 6, an occupant's gesture 610, such as, but not limited to, anextended arm pointing in a direction, is depicted along with adetermined gaze 612. Two vehicles 606 and 608 are depicted as beingoutside of the occupants of vehicle, as indicated by a line ofdemarcation 604 differentiating between a region inside the vehicle anda region outside of the vehicle. It is anticipated that a human occupantmay instruct the autonomous vehicle to perform an activity, such thatthe instruction may be ambiguous. For demonstrative purposes, a specificexample may be an occupant instructing an autonomous vehicle in avicinity of two vehicles 606 and 608 to park “next to the car.” A verbalcue alone (such as a verbal instruction to park “next to the car”) mayprovide insufficient information for the autonomous vehicle, as multiplecars may be present, and therefore it cannot be determined which car ismeant by the occupant. The ability to receive and understand a visualcue alongside a verbal cue, however, may allow the intelligent agent tomuch more accurately understand the occupant's intentions orinstructions. For example, the occupant's gaze (a visual cue) mayprovide additional clues as to the object of the occupant's attention.In this case, the physical embodied agent 602 may detect a first vector612 associated with an occupant's gaze and a second vector 610associated with an occupant's gesture. The two vectors may be evaluatedfor a point of intersection, which may indicate an area of theoccupant's attention. This is not limited to objects or regions outsideof the vehicle but may also include objects or regions within thevehicle as well. That is, the occupant point or direct attention to oneor more objects or regions within the vehicle, and the intelligent agentmay be configured to identify from the occupant's gestures and/or gazethe object or area to which the occupant's attention is directed.Moreover, the detection of an occupant's gaze pay permit the embodiedagent to engage in shared focus with the occupant as a communicativedevice.

FIG. 7 depicts an additional configuration of the first aspect of thedisclosure. In this case, the vehicle occupant 702 is present withattention drawn to a region of the vehicle. One or more image sensors704 receive images of the vehicle occupant 702. The images aretransferred to one or more processors 706, which determine from theimages the occupant's gaze. The one or more processors 706 map theoccupant's gaze to an area or point of the vehicle and control aprojector 708 to project a visual tag 710 on the area corresponding withthe occupant's gaze. By projecting on that area, it becomes unnecessaryfor the vehicle occupant to turn the occupant's gaze elsewhere tocommunicate with the autonomous vehicle while having a vehicle focalpoint.

FIG. 8 depicts an additional configuration of the second aspect of thedisclosure. In this case, a vehicle occupant 802 is within a vehiclewhile turning the occupant's gaze toward a focal point. The one or moreimage sensors 804 receive images of the vehicle occupant 802 andtransfer the images to the one or more processors 806. The one or moreprocessors 806 derive from the image data the occupant's gaze, which ismapped to a point or area of the vehicle. A screen or displaycorresponding to the mapped point or area is selected as a screen ordisplay on which the visual tag is to be displayed. The one or moreprocessors 806 control the selected display 808 to display the visualtag. The vehicle may be equipped with one or more displays, which may belocated anywhere throughout the vehicle the displays may be multipledistinct displays; portions of one or more displays; flat displays;curved displays; bendable displays; or otherwise.

FIG. 9 depicts an additional configuration of the third aspect of thedisclosure. The vehicle occupant 902 is within a vehicle while turningthe occupant's gaze toward a focal point. In this case, the focal pointis the physical embodied object. The one or more image sensors 904 areconfigured to receive images of the vehicle occupant 902 and to transfersaid images or corresponding image data to one or more processors 906.The one or more processors 906 determine from the images or image data auser occupant's gaze. The one or more processors may control thephysical embodied object 908 to perform one or more actionscorresponding to the determined gaze of the occupant. For example, theone or more processors 906 may control the physical embodied object 908to turn its torso, head, or otherwise toward the occupant or gesture tothe occupant.

FIG. 10 depicts a processing workflow. One or more cameras areconfigured to perform image acquisition 1002, and the correspondingimages or image data are transferred along two paths. The first pathleads to eye tracking determination 1004, at which the occupant's eyesmay be detected within the image data. The eye tracking information isevaluated by an eye direction estimator 1006, which determines adirection of the occupant's eyes. Regarding the second path, the imageacquisition information is delivered to a face detection unit 1008,which isolates the occupant's face within the images or image data. Theisolated face information is delivered to a head pose estimator 1010,which determines a head pose configuration relative to a reference pointwithin the system or vehicle, or other head directional informationrelative to a fixed point. The eye direction estimation and head poseestimation information are delivered to the fusion and adaptation module(“FAM”) 1012, which synthesizes the eye direction information and headpose information to determine an occupant gaze.

FIG. 11 shows elements of a gaze calculation. According to one aspect ofthe disclosure, the system described herein may calculate a precise gazeof an occupant. According to another aspect of the disclosure, however,a precise gaze calculation may be unnecessary, and therefore it maysuffice to omit one or more of the six degrees of freedom within thecalculation, such omitting any of movement along an x-axis, a y-axis, az-axis, roll, yaw, and pitch. For example, as described herein, it maybe possible to calculate a gaze of sufficient accuracy using only thehead position and the yaw angle of the eyeballs, as depicted in FIG. 11.In this figure, the dashed lines 1106 and 1108 represent perpendicularplanes slicing through the occupant from a bird's eye perspective. Thesolid arrows 1104 indicate the direction the occupant is actuallylooking. The dashed lines 1102 along with angle ‘m’ indicate the yawangle of the head with respect to a reference point. In this case, thereference point is, for example, 12 o'clock. Similarly, angle ‘n’ is theyaw angle of the eyeball. The sum ‘m+n’ provides the gaze direction inreference to the occupant's reference point. As will be described laterherein, this aggregated angle for gaze determination may be calculatedby the FAM.

FIG. 12 depicts an operation of the FAM block according to an aspect ofthe disclosure. Following the execution of the procedure 1202, binarystate variables ‘x’ and ‘y’ are initialized to zero in the FAM, as shownby 1202 and 1204. These states permit conditional fusion in FAM, whichmay be desired in cases in which the yaw angles for the eyeball and/orthe head may not be available. The yaw angle of the eyeball (i.e. ‘n’)is determined by the gaze estimator and may be calculated within the[−90,90] degree range. Similarly, the yaw angle of the head (i.e. ‘m’)is received from the head pose estimator block estimator, and may alsovary between [−90,90] degrees. At the fusion stage, it is determinedwhether the eyeball yaw angle is available 1208 and whether the head yawangle is available 1210. If the eyeball yaw angle n is available 1210,then x is set to 1, 1212. If the head yaw angle is available 1216, theny is set to 1, 1218. If either ‘m’ or ‘n’ are not available, only theavailable angle is forwarded to the Passenger Interaction Engine (“PIE”)block 1222. If neither of the angles are available, the output value(i.e. ‘q’) is initialized to 360 degrees 1220, which is outside thevalid range for q of −90 to 90 degrees, and thus indicates anunavailability of yaw angles to the PIE block. The FAM block may beconfigured to continuously update angle ‘q’ 1224, or it may calculate qonce per activation, depending on the context of operation. Thisparameter can be made available as an option to the system designers.When the updates discontinue, then procedure ends 1226.

FIG. 13 depicts the PIE according to an aspect of the disclosure. ThePIE block may accept input from the FAM block, the occupant seatingposition related sensor information, and the vehicle's hardwareconfiguration information. Optionally, audio based context informationcan be provided to PIE block in order to enhance its controller dataprovisioning capabilities (i.e. controller data output can be calculatedbased on audio as well as visual information). Upon activation 1302, thePIE block receives an audio prompt or a fused yaw angle availability1304, and acquires the seating position of the occupant 1306A, as wellas the occupant's fused yaw angle 1308 as provided by the FAM block. ThePIE block then identifies which aspect or aspects of the disclosure aresupported by the vehicle, whether projection of a visual tag 1310,displaying of a visual tag on one or more screens 1312, or interactionwith an embodied agent 1314. In the event that no such support isavailable, the procedure ends 1316. The steps corresponding to 1310,1312, and 1314 may operate in parallel, such as in a multi-threadedapplication. In the case of tangible device support, there will be oneoutput device with a fixed location inside the vehicle. Therefore,identification of a target location for animating the agent may beirrelevant. The PIE simply generates the agent's motion vector data 1330and creates a data frame compatible with the subsequent AEC block thatwill activate the tangible device according to the vector dataspecified. The vector data may be updated depending on the context ofthe interaction between the agent and the occupant (as a non-limitingexample for demonstrative purposes, the embodied agent may wave at theoccupant as it turns its head to face the occupant, when the occupantenters the vehicle) 1336.

In the case of dynamic projection and fixed screen embodiments 1312,there may be multiple candidate locations for the display of the visualtag. To manage the possibility of multiple locations, the availablescreens are first identified, and their locations within the vehicle areascertained 1326. The preferred location is then identified based onoccupant's gaze and the seating position 1328. With this information,the tag's fixed screen visual update data is generated 1324, thecombined AEC data frame is generated 1332, and the combined frame isforwarded to the AEC 1334. In the event that dynamic projection issupported 1310, one or more suitable projection locations are identified1318, and the desired projection location is identified from thepotential projection locations based on the occupant's seating positionin gaze 1320, and the visual tag's fixed screen visual update data isgenerated 1322. The combined AEC data frame is generated 1332, and thecombined frame is forwarded to the AEC 1334.

FIG. 14 depicts a procedure for identifying a desired location forprojection or display of the visual tag. In the event that a pluralityof screens is used, any number of screens may be implemented, withoutlimitation. For the sake of convenience, three screens are depicted inFIG. 14; however, the number of screens should not be understood asbeing limited to three. The procedures described herein may beimplemented with one or more occupants sitting at any location withinthe vehicle. In this figure, the vehicle has three screens, screen one1402, screen two 1404, and screen three 1406. The occupant is seatedbehind and between fixed screen to 1404 and fixed screen three 1406, butthe occupant's gaze is directed toward fixed screen one 1402. Based onthe annotations and representations in this figure, the following tablelists the relevant critical parameters and their definitions beforeproviding the calculation details:

Parameter Definition Known/Unknown x Shortest distance between themounted screens Known (part of the and the occupant′s seat vehicle′sbuilt-in attributes) y Separation between the two screens Known (part ofthe vehicle′s built-in attributes) w Distance of occupant seatingposition to Known (part of the nearest screen vehicle′s built-inattributes) q Fused yaw angle for the occupant′s gaze Known (provided byFAM) a Yaw angle when occupant looks directly at Unknown (calculatedbased fixed screen one on seating position) b Yaw angle when occupantlooks directly at Unknown (calculated based fixed screen two on seatingposition) c Yaw angle when occupant looks directly at Unknown(calculated based fixed screen three on seating position) k Days changeeffort angle when current Unknown (calculated based occupant gaze needsto switch to fixed screen on seating position and one current gazeangle) m Days change effort angle when current Unknown (calculated basedoccupant gaze needs to switch to fixed screen on seating position andtwo current gaze angle) n Days change effort angle when current Unknown(calculated based occupant gaze needs to switch to fixed screen onseating position and three current gaze angle)

Angles ‘k’, ‘m’ and ‘n’ may be compared to determine the angle with thesmallest magnitude. The desired screen may be determined as the screenthat will require the least effort for the occupant to shift theoccupant's gaze, given the seating position and the current gazedirection. The number of calculations needed can be reduced through aprocess of elimination based on the sign of angle ‘q’ as indicated inFIG. 14. In the shown example, the sign of ‘q’ is negative, andtherefore all the screens that give a positive ‘q’ when viewed by theoccupant can be eliminated as candidate screens, as the occupant willhave to spend more effort to redirect the occupant's gaze. Therefore,angle ‘n’ can be eliminated as a candidate screen, as fixed screen 3requires more gaze redirection than Fixed Screen 1 or Fixed Screen 2. Asthe next step, the remaining angles ‘k’ and ‘m’ are calculated asfollows.

$\begin{matrix}{a = {{atan}\left( \frac{w + y}{x} \right)}} & (1) \\{b = {{atan}\left( \frac{w}{x} \right)}} & (2) \\{k = {{{q} - a}}} & (3) \\{m = {{{q} - b}}} & (4)\end{matrix}$

Then the selection of the desired screen to display the embodiment canbe made as follows:

If k<m, then use fixed screen 1  (5)

If k<m, then use fixed screen 1  (6)

The decision for case k=m is determined in exactly the same way as whenangle ‘q’ is not made available by the FAM block (i.e. when q=360degrees) In such cases, the embodiment target device can be selectedbased on the seating position of the occupant alone.

In the case of dynamic projection and fixed screen embodiments, becausethere are likely to be multiple candidate locations for the embodiments,identification of the desired location based on occupant gaze and theseating position will be required. In addition, the FAM may also beconfigured to select a desired location in situations in which the gazeestimation and/or the head pose estimation may not be available, asthese are independently calculated and forwarded to FAM. Such cornercases are handled at the fusion stage in FAM.

FIG. 15 depicts a determination of a preferred display location in theevent that one or more angles between the occupant and a displaylocation are not available. In FIG. 14, Fixed Screen 3 could beeliminated as an option, thereby leaving Fixed Screen 1 and Fixed Screen2 as potential options for a display location. In this situation, FixedScreen 1 or Fixed Screen 2 may be selected as follows:

A=√{square root over (x ²+(y+w)²)}  (7)

B=√{square root over (x ² +w ²)}  (8)

If A>B, then use fixed screen 2  (9)

If A<B, then use fixed screen 1  (10)

If angle ‘q’ is not available at the activation of PIE block operations(i.e. q=360 was sent to PIE input), then it may be necessary toadditionally consider Eq. 11.

C=√{square root over (x ²+(y−w)²)}  (11)

The decision process would then be modified as:

If min(A,B,C)=A, then used fixed screen 1  (12)

If min(A,B,C)=B, then used fixed screen 2  (13)

If min(A,B,C)=C, then used fixed screen 3  (14)

where min(.) gives the argument with the minimum magnitude.

The above calculations within the PIE block can be repeated to ensuretimely updating of the fixed screen display and the projection of thevisual tag, based on occupant's gaze and the seating position changes asindicated in FIG. 13. Some implementations of the PIE block may permitimproved decision-making, such as where the fusion takes certainocclusions inside the vehicle between the occupant and the candidatescreens/projection locations into account before choosing the targetdisplay device and/or display location. This would require the PIE blockto work in tandem with various object recognition sub-systems within thevehicle. The fusion algorithms disclosed herein can be applied tosupport such extensions.

FIG. 16 depicts the AEC, which activates the visual tag or physicalembodied agent once the PIE block determines the display location andgenerates the required update data, all of which are integrated into anAEC data frame. FIG. 16 shows the operation of AEC, which is able tosupport projection of the visual tag, display of the visual tag on oneor more displays, use of the physical embodied agent, or any combinationthereof. As depicted herein, once the procedure begins 1602, it isdetermined whether a PIE update is available. If no update is available1604, then a loop is created until an update is provided. Once an updateis available 1606, the combined AEC data frame is parsed 1608. It isdetermined which modalities are supported by the vehicle, whetherdynamic projection of the visual tag 1610, displaying on one or morescreens 1622, or use of a physical embodied agent 1632. In the eventthat dynamic projection is available 1610, the target projectionlocation or selected display location 1612 is obtained, and the targetprojection or selected display dimensions are configured 1614. Aprojection data update of the visual tag is updated 1616, and therendered projection output is displayed at the selected location 1618.Once this is completed is analyzed whether any additional PIE updateinformation is available 1620.

In the event that the visual tag is to be displayed on one or more fixedscreens 1622, the target screen locations are determined 1624, as arethe resolutions for one or more of the target screens 1626. An updatedvirtual tag information, if available, is provided for each screen onwhich the virtual tag will be displayed 1628. The virtual tag is thendisplayed on each screen that is selected 1630. It is noted that, asdescribed herein in at least 1630, it may be contemplated that thevisual tag would be displayed on more than one screen. According to oneaspect of the disclosure, a specific screen may be selected fordisplaying the visual tag based on the methods described herein. Asingle location within the single screen may be selected for displayingthe visual tag. According to another aspect of the disclosure however,it may be desirable to display the visual tag on a plurality of screensas described in 1630.

In the event that a physical embodied agent is used 1632, the agent'smotion vector update is obtained 1634, and target movements on the agentare activated 1636.

In addition to the embodiment data updates, the AEC block also receiveshardware related information directly from PIE, such as targetprojection dimensions, locations, and screen resolutions. According toanother aspect of the disclosure, such information may also be providedto the AEC directly from other sub-systems in the vehicle, as this maybe the preferred implementation for a vehicle manufacturer. The AECblock may also monitor the output of the PIE block to ensure that newupdates are promptly applied to relevant devices to foster a smooth userexperience.

Similarly, the one or more processors 1804 may belocated separately from the physical embodied agent 1801, or they may belocated as part of the physical embodied agent 1801.

FIG. 19 depicts a method of displaying a tag including receiving one ormore images of a vehicle occupant 1902; determining a gaze direction ofthe vehicle occupant from the one or more images 1904; selecting adisplay location corresponding to the determined gaze direction 1906;and controlling an image display device to display a tag at the displaylocation 1908.

As autonomous vehicles are developed, it is becoming more important forautonomous vehicles to develop the capability of understanding theintentions of vehicle occupants. Some intentions are simplistic and thusreadily understandable. For example, it is a relatively straightforwardtask for an occupant to inform the vehicle of a desired destination atthe beginning of travel. For example, an occupant may instruct a vehicleto travel to a specific destination or to use a specific route, whichcan be achieved with a simple verbal command. This interaction mayrequire only speech recognition and an ability to cross-referencelocations detected from the speech with actual geographical locations,such as being able to recognize a destination, and then identify thedestination and a route thereto in a database. However, someinteractions between occupants and the vehicle are more challenging,such as spontaneous ad hoc interactions, for example, as with en routemodifications due to traffic problems or changes in the desireddestination. Such situations require more nuanced conversations that maybe beyond the capabilities of even the most robust speech to textsystems. This may be due at least to the fact that information relatedto the occupant's intention is contained in modalities outside of thetext itself, such as the expressions and gestures of the occupant.

The best results may be obtained by developing autonomous vehicles thatare able to understand communication in the normal ways that humanscommunicate with one another. If for no other reason, this may owe tothe fact that occupants can be assumed to have the most experiencecommunicating with other persons. This may go beyond the simple text ofa sentence, and include additional resources such as tone of voice,gesture, features of the environment, and emotional displays (bothfeigned and sincere). Removing any of the non-lexical features from theinput to an autonomous vehicle agent may carry an unnecessary cost.

Devices that are sufficiently context aware can be a part of anautonomous vehicle system such that it can support fully naturalcommunication. Such a system may have the ability to recognize speech,to identify the speaker, and to recognize emotional timbre, etc. Theinput must also include vision to support the use of gesture and otheraspects of contextual awareness (e.g., seeing a phone in the occupant'shand or the building toward which the occupant is pointing). Such visionmay be used as described herein in conjunction with speech todisambiguate the spoken reference.

The one or more image sensors may be any kind of image sensors, whichare capable of obtaining an image of the vehicle occupant or occupants,without limitation. Furthermore, and depending on the desiredconfiguration, the one or more image sensors may be configured to obtainimages of one or more regions and/or objects in a vicinity of a vehicle.Any one or more image sensors may be individually capable of receivingimages from both inside the vehicle and outside the vehicle, or they mayreceive images from either inside the vehicle or outside the vehicle andmay deliver said images to the one or more processors for synthesisany/or any further processing. The images sensors may include, forexample, a still camera, a video camera, a depth camera, an infraredcamera, lidar, or radar. The one or more image sensors may be located atany position or combination of positions within the vehicle. Where aplurality of image sensors are used, the image sensors may be locatedgenerally within a single place on the vehicle, or may be located inmultiple places, so as to obtain different vantages of one or morevehicle occupants. Where a plurality of image sensors are used, the datafrom the image sensors may be assessed separately from each imagesensor, or the image data may be aggregated to form a singular image,which is then assessed by the one or more processors. The dataaggregation may occur given any known image combining or imageaggregation technique.

The one or more processors may be any type of processor whatsoever,which are capable of performing the tasks described herein. The one ormore processors may be located anywhere within or external to thevehicle, depending on the implementation. Where the one or moreprocessors are located within the vehicle, they may be located withinthe embodied agent, within the image display device, or anywhere elsewithin the vehicle. Where the one or more processors are locatedexternal to the vehicle, they may be located in any place whatsoever,and the vehicle may be configured to transmit data such as image sensordata to the one or more processors, and to receive from the one or moreprocessors information for projecting or displaying the visual tag, orinformation for execution of the embodied agent.

The gaze direction may be determined with respect to any location.According to one aspect of the disclosure, one or more fixed locationswithin the vehicle may be dedicated as a fixed location relative towhich the gaze is determined. Determining the gaze may include anycombination of determining a position of a vehicle occupant, determininga body orientation of the vehicle occupant, determining a headorientation of the vehicle occupant, and/or determining the eyeorientation of the vehicle occupant.

The display location may be any surface on or within the vehicle. Thedisplay location may include, without limitation, a dashboard, awindshield, a window, a panel, a wall, a door, a ceiling, or any otherportion of the vehicle.

The visual tag may be displayed or projected at any size or resolution.According to one aspect of the disclosure, the size and/or resolution ofthe visual tag may be selected based on any of a distance between thevehicle occupant and the display location, a projection quality of thedisplay location, or any other feature.

As described herein, the gaze direction may be calculated from at leastone of an eye position, a head position, a body position, a physicallocation of a vehicle occupant, or any combination thereof.

According to one aspect of the disclosure, the calculations for gazedirection may be simplified by calculating, where possible, a head yawand eye yaw. This may be at least because the possibilities fordisplaying or projecting the visual tag may be greater horizontally thanvertically. Otherwise stated, there may be many surfaces of roughly thesame height, or roughly along the same horizontal plane, on which thevisual tag may be projected or displayed; however, depending on thevehicle configuration, there may be fewer surfaces along a verticalplane on which the tag may be displayed. As such, it may be sufficientto calculate a head yaw and eye yaw, which may provide information abouta location within the given horizontal plane at which the visual tag mayideally be projected or displayed.

Alternatively, any or all of the six degrees of freedom may becalculated with respect to any combination of eye position, headposition, body position, or any combination thereof, and thisinformation may be used to select a display location.

According to one aspect of the disclosure, the image display device maybe a projector, which is configured to project the visual tag onto asurface. The projector may project the visual tag at any size orresolution desired. The one or more processors may be configured tomodify the projection information to account for anything other than aprojection surface that is perpendicular to the projection direction.That is, where the projection surface is flat but angled such that it isnot perpendicular to the line of projection, the one or more processorsmay be configured to modify the projection data such that the projectionon the angled projection surface appears to the vehicle occupant as anunmodified visual tag. Where the projection surface is uneven, such aswith a curved surface, the one or more processors may be configured tomodify the projection data such that the projection on the curved oruneven surface appears to the vehicle occupant as an unmodified visualtag. This modification may be performed using any known methodincluding, but not limited to, any known projection mapping technique.

According to another aspect of the disclosure, the image display devicemay be a display, such as a screen that is configured to display one ormore images. The display may be located at any position within thevehicle including, but not limited to, within a central console, on arear surface of a seat, on a wall, on a ceiling, or anywhere else withinthe vehicle whatsoever. A plurality of displays may be arranged withinthe vehicle, such that selecting the display location includes selectinga particular display on which the visual tag will be displayed.Furthermore, selecting a display location may include selecting aparticular point or points on the selected display on which the visualtag will be displayed. Where desired, a plurality of displays may beselected to jointly display the visual tag. Where this occurs, thevisual tag may be repeatedly displayed on the plurality of displays,such that an identical or nearly identical image is found on each of thedisplays, or the visual tag may be divided, such that a portion of thevisual tag is displayed on a first display, and a portion of the visualtag displayed on another display. This technique may incorporate anynumber of displays, as desired. The displays may be any kind of displayswhatsoever, whether LCD, OLED, flat, curved, flexible, or otherwise.

According to another aspect of the disclosure, the system describedherein may be equipped with the ability to coordinate a movement of anoccupant within a vicinity of the vehicle. In normal human-to-humaninteraction, it is common to point or otherwise gesticulate toward anobject that is the subject of a conversation. If communication between ahuman and a vehicle is limited to entering data into an interface, suchas a screen or control, or by using voice cues devoid of physicalinformation, such gestures cannot be included in communication with thevehicle.

It is thus anticipated that the vehicle may derive from the one or moreimage sensors a direction of a gesture of an occupant, such as adirection of pointing. Coordinates or headings for the direction may beobtained, which may be a vector, with either a calculated orpredetermined length, a line extending in the direction of pointing, orotherwise. The vehicle may be equipped with one or more image sensors,which are configured to obtain images from the vicinity of the vehicle.The one or more processors may be configured to correlate a direction ofthe pointing using the vector, line, or otherwise, with the image dataregarding the vicinity of the vehicle. Using this technique, the vehiclemay be able to correlate a gesture with an object, such as pointing to avehicle, a parking spot, a street, or otherwise. The one or moreprocessors may be configured to incorporate this data into any availablespeech recognition, such that the vehicle may be assisted inunderstanding the occupant's intentions. For example, an occupantstating “Park over there” while pointing to a parking space may haveprovided the vehicle within insufficient information to complete thedesired task, if only text or only gesture are considered; however, ifthe vehicle is able to understand both text and gesture, the vehicle maybe equipped to locate the intended parking spot and carry out thecommand to park at that location.

Similarly, the vehicle may be equipped to correlate an occupant's gazewith an external location. This may be carried out in much the same waythat the vehicle correlates a gesture or pointing with an exteriorlocation. The vehicle may use any of the techniques described herein toidentify a direction of an occupant's gaze, and may extend the directionof that gaze outward beyond the vehicle, until its intersection with anobject is detected by one or more image sensors obtaining image dataabout the vicinity of the vehicle.

Using the above-described techniques, the vehicle may also correlate anoccupant's gaze and an occupant's gesture to identify an externallocation. In this case, a direction of the occupant's gaze and adirection of the occupant's gesture may be correlated with informationabout the vicinity of the vehicle to identify an object or locationexternal to the vehicle. Because an occupant's gesture, such as with anupper extremity, originates from a different physical place than anoccupant's gaze, vectors and/or lines extending in the direction of thegaze and pointing may ultimately intersect. This point of intersectionmay correspond with an intended object or location. A vector or linecorresponding to a determined gaze, and a vector or line correspondingto a determined gesture, may be in two different planes and would thusnot intersect. According to one aspect of the disclosure, one or both ofthe vectors and/or lines may be modified such that the vector or linecorresponding to the determined gaze and the vector or linecorresponding to the determined gesture may be modified to be within thesame plane and thus intersect.

According to another aspect of the disclosure, the vehicle may beequipped with a physical embodied agent. The physical embodied agent maybe a physical, three-dimensional representation of the vehicle and/orits artificial intelligence. The physical embodied agent may take anyform whatsoever, including a three-dimensional variety of any formdescribed herein with respect to the visual tag.

Upon determining an occupant's gaze, the one or more processors maycontrol the physical embodied agent to execute a routine. The routinemay be any routine whatsoever. Non-limiting examples of said routine mayinclude turning the physical embodied agent to face the occupant,causing the physical embodied agent to perform one or more gestures,causing the head of the physical embodied agent to turn toward theoccupant, or causing the eyes of the physical embodied agent to turntoward the occupant, or toward a third location to enable a shared focuswith the occupant.

The physical embodied agent may include one or more joints or movable orbendable portions. The physical embodied agent may be configured toadjust the one or more joints or movable or bendable portions so as tochange position and/or posture within the vehicle, or to gesticulate inany way. The joints may be configured in a manner such as to mimic orapproximate human movement, or in any other manner desired.

According to one aspect of the disclosure, the projector may be ahologram projector, and the virtual agent may be projected in the formof a hologram. In this case, the one or more image sensors will detectthe head position and an eye position as described herein, and thedetected head position and an eye position will be mapped to an area ofthe vehicle. The one or more processors may be configured to cause thehologram projector to project the hologram of the virtual agent in anarea corresponding to the mapped area, as determined from the calculatedhead position and an eye position. Where the hologram is configured as athree dimensional hologram, the hologram of the virtual agent may berotated, such that the virtual agent appears to face the vehicleoccupant. This may include rotating the virtual agent any number ofdegrees. Alternatively, the virtual agent may be rotated to appear tolook at or point to an object in a direction other than the vehicleoccupant.

Although the methods and procedures described herein have been detailedwith respect to a vehicle, such as an autonomous vehicle, the methodsand procedures described herein may also be applied to situations otherthan in the vehicle, such as in buildings, in public spaces, orotherwise. The one or more image sensors may be placed in any locationto obtain image data of a person, and the person's head position and aneye position may be determined in the manner described herein. Thecombined head position and an eye position may be used to determine agaze of the person, and a location may be selected for displaying anintelligent agent based on the determined gaze. Whereas this has beendescribed with respect to a vehicle, the person may be located in anyplace whatsoever, whether in a building, or outside. Where a physicalembodied agent is used, the physical embodied agent may be configured toperform one or more activities or trigger one or more activities basedon the determined gaze in the manner described with respect to thephysical embodied agent in the vehicle herein. Possible nonlimitingexamples of extra-vehicular places where this technology may be usedinclude stores, commercial establishments, schools, public buildings,private buildings, public outdoor spaces, private outdoor spaces, andhomes. In a multiple vehicle-occupant scenario, the projection and/ordisplay of the embodied agent may be performed such that multipleembodied agents are projected or displayed. That is, an embodied agentmay be displayed for each of multiple vehicle occupants. Thus, the oneor more processors may be configured to display, control, animate, orotherwise operate multiple embodied agents concurrently. In somescenarios, such as in the event that a projection mapping technology isused with multiple occupants, it may be undesirable to use a singleembodied agent for two or more vehicle occupants, due at least toprojection mapping's dependence upon viewing angle.

Alternatively, in a multiple vehicle-occupant scenario, it may bedesirable to select a single location for projection of the embodiedagent. For at least the reasons stated above, and particularly where aprojection mapping algorithm is employed, selection of a single locationfor multiple occupants may create additional challenges, since effectiveexecution of the projection mapping technology may be dependent on aviewing angles of the one or more occupants. This is, if an idealprojection mapping is implemented for a specific viewing angle of asingle occupant, the resulting projection may appear skewed or otherwisedistorted from a viewing angle of another occupant. According to oneaspect of the disclosure, in the event that a plurality of occupants arepresent in the vehicle, and a single projection of the embodied agentfor two or more occupants is desired, a single projection location maybe selected as a compromise between two or more ideal projection angles.The single projection location may be selected to provide an acceptablerepresentation of the embodied agent for the two or more occupants. Theprojection location may be selected based on at least one of theoccupants' gazes, the occupants' viewing angles of the projection, acalculated distortion of the projection in light of the occupants'viewing angles, and any combination thereof.

According to another aspect of the disclosure, and in amultiple-occupant situation, the one or more processors may beconfigured to determine from images of two or more occupants a jointoccupant gaze. In conversation, humans may engage in joint gaze, whereinthe humans direct their gaze to a common point of focus, such as lookingat a single object, at a single region, or a common space. This mayoccur, for example, when humans pass an object from one human toanother, as they may direct their gaze from a face of a conversationpartner to the object that is being passed. The one or more processorsmay be configured to determine a location of joint occupant gaze. Wherean area of joint occupant gaze is present, the one or more processorsmay be configured to configure the embodied agent to also appear todirect its attention to the area of joint gaze. That is, the body, head,and/or eyes may appear to turn toward the area of join occupant gaze.
